4, Northgate Street

4 Northgate Street is a three-bay house of two storeys and attic, dating from the late 17th century with alterations to the main elevation in the late 18th century.

The building is single-depth on plan with a slightly irregular projecting rear wing to the north. It is built from red brick laid in Flemish bond with a plain clay tile roof.

The main elevation is set on a slightly projecting plinth and has a string course between the first and second floors and a moulded cornice at the eaves. A plain pilaster marks the junction with number 6 to the north. The central entrance doorway contains a six-panel flush door in an opening with a semi-circular fanlight, set under a projecting hood carried on console brackets. The windows are six-over-six sashes, positioned under rubbed brick flat arches with slightly projecting painted keystones. The roof has two gabled dormers, each fitted with side-hung timber casements.

The centre of Warwick was severely damaged by a major fire on 5 September 1694. The fire began to the west of Northgate Street but spread rapidly after householders moved smouldering furniture to St Mary's Church at the south end of the street. The church caught fire, and flames then spread quickly along Northgate Street, destroying all houses on the east side and damaging those on the west. Some rear walls on the east side appear to have survived. The houses were rebuilt immediately following the fire before the end of the 17th century, though later 18th-century alterations were made, including much of the detailing to the main elevations. The houses originally served as substantial private dwellings but by 1896 several had converted to commercial and professional use and lodgings, though some remained private family homes. By the early 21st century the houses were in use as offices for district council departments, together with later 20th-century offices built to the rear.

The building has group value with the other listed buildings along Northgate Street.
